Our Nano Indentation technique confirms to hardness testing ISO 14577.
The typical experimental graph of load (P) versus depth (h) is presented in figure above. In this method hardness of a sample is calculated as:

where AC - is projected contact area at maximal indentation load Pmax.

Reduced elastic modulus value is calculated as:

where constant depends on indenter geometry, and
Contact stiffness S is determined by the angle of slope of the tangent to the unloading curve in the point Pmax. Contact area at maximal load AC is determined by indenter geometry and contact depth hc. It is described by the indenter area function AC = f (hc).
